To all'whom it concern:-

Be 1t known thatl, LEE CALLAHAN, a citizen of the United'ifitates, residing at San Diego, in the countyof San .Diego and State of California, haveinvented newand useful Improvements in Material-Clransferring Apparatus, of whichjtheQ-following is a specification.

My invention ei'tains to apparatus for supplying materlals to buildlngs in the course of erection-Z and it has for its general object to provide an apparatus calculated to be used to advantage in transferring concrete or other plastic material from a suitable source offsupply'to the "points desired on a building'thatis being built.

Another general object of the invention is to provide an apparatus of the kind stated adapted more es ecially for use when a fication, in which :j-

Figure 1 is a side elevation of the appara-' tus constituting the best practical embodiment ofmy invention of which I am cognizant. Fig. 2 is an enlarged detail view of the plastic-material'boom with the conduit omitted. Figs. 3 and 3* are enlarged detail views showing the manner in which the horizontal tracks are adjustably fixed at different points in the height of the tower. Fig. 4 1s a cross-section showing one track and the arrangementof one boom-carriage therein. Fig. 5 isga. detail horizontal section, and Fig. 6, a detail elevatipn of a part of the tower. Fig. '7 is'an enlarged horizontal section of the tower. Fig. 8 is an enlarged detail view, partly in section and partly in elevation; showing one of the open pans of the apparatus and the support thereof Figs. 9, E10;- and 11 are enlarged detail views illustrativeof conduit connec tions hereinafter referred, to.' Figs. 12"and 13 are enlarged detail views showing the manner in which'I prefer to fasten the lower ends of the corner uprights of the tower. Fig. 14 ,is a detail crosssection showing the arrangement of the conduit in the plastic-material boom. Fig. l5 is an enlarged detail elevation of the carriage or traveler on the construction boom. Fig. 16 is a transverse section taken in the plane indicated by the line 1616 of Fig. 15.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A isjthe fixed tower of my novel apparatus. The said tower may be of any general construction consonant with the purpose of my'invention without involving departure from the same as claimed. I prefer, however, to construct the tower of suitable metal, and in twelve-foot, superposed sections, and to have it comprise corner uprights a, of angular form in cross-section, and inclined braces b and horizontal braces 6 of similar form in. cross-section, connecting the corner uprights in such manner as to make the tower of rectangular form in crosssection. I also prefer to fix the tower in position in-the manner illustrated in Figs.

1, 12 and 13-that is to say, by arranging the corner uprights a of the lowermost section seats 0 arranged on concrete bases 03, embedded in the ground, and by connecting the lower ends of said uprights and the seats a through the medium of bolts 6 with anchors j held in the bases d. It will also be understood in this connection that guy cables 9, Fig. 1, extending from the upper end of the tower to fixed objects located about the tower, may be and preferably are employed to assist in maintaining the tower in upright position.

The tower is increased in height as the construction of a building progresses by adding twelve-footsections, and each added section is fixedly connected with the one below' it, preferably through the medium of fish-plates hbest shown in Figs. 5 and 6.

y Arranged in the tower A and connected by struts i with the corner uprights a thereof, arehpright rails B, Fig. 7, and at this point I would have it understood that when a section is added to the tower to increase the height thereof, sections will be added to the rails 13' to correspondingly increase the neighbor the same. The rails are (le signed to coiiperate with and guidea skip C,

the office of which is to hoist plastic material to a desired point in the height of the tower and there dump the same. The skip C and the means for raising and tripping the same are preferably, though not necessarily, of the type disclosed in the Letters-Patent of one Wallace, No. 830,385 of September 4, 1906, andI have therefore deemed it sufficient to show the skip alone diagrammatically herein. I would also have it,understood that when desired ,theskip may be dumped by a man stationed on the tower at the point where the skip is to be discharged of its contents, without afiecting my invention.

Removably arranged in the tower and suitably supported, preferably by resting on one of the horizontal braces and by being hung from struts 2', is a floor or platform D, and suitably supported above said platform D is a chute E adapted to receive plastic material from the skip C, and a hopper F' arranged to receive plastic material from the chute, which hopper F is provided with a contracted discharge is and a gate I through the medium of which the before mentioned attendant can control the passage of plastic material from the hopper F. Arranged below and adapted to receive plastic material from the discharge of the hopper F is an open pan G to which is fixed a support H, Figs. 1 and 8. The said support H' terminates at its lower end in a ball I which is disposed in a complementary socket J on on the floor or platform D, and hence it will be manifest that the contracted discharge pipe G slipped in or on the reduced end of the pan G may be pointed in various directions according to the points on the building at which the plastic material is to be delivered to forms. as hereinafter described in detail. The said pipe G, which extends outside the tower A and is preferably supported by wires m, Figs. 1 and 7, or other suitable means, is positioned to supply plastic material to an open pan K suitably connected with a conduit L, hereinafter described.

Fixed to the tower A at points adjacent the two forward corners thereof and extending throughout the height of the tower are Z-bars M, Figs. 3 and 7 so termed because of their shape in horizontal section. These bars M are designed for the engagement of Z-shaped hooks N on horizontal, vertically adjustable tracks P and R which are arranged one above the other and extend across the front.side of the tower. Each track is adjustably fixed to the tower and against gravitation by the means best shown in Figs. 8, 3 and 7that is to say, through the medium of cast iron blocks S riveted to its hooks N and havin notches T, and locking pieces U detacha ly connected to the corner uprights a of the tower, and having lugs V which occupy the said notches T. From this it follows that each track may be fixed to the tower at various points in the height thereof, and in this connection I would have it understood that any suitable means maybe em loyed to raise and lower either track P or l t such, for instance, as a cable (not shown) connected to the track and passed through a pulley block (also not shown) fastened at or near the top of the tower. Each of the tracks P and R is equipped with a boom -carriage W, best shown in Fig. 4, having an eye m, and antifriction balls 12. for easmg the movement of the carriage, and each boom-carriage is provided with end sockets to receive eye-bolts connected by chains 1' with eye-bolts s whic in turn, are connected to op osite sides of the tower, this with a view 0 retaining the boom-carriage at one end or the other of its respective track. It will be understood here that each track has end plates m or other stops to limit movement of its boom-carriage and that the eye-bolts p are turned through openings in saidend plates on and into the threaded sockets in their respective carriage.

X is the plastic-material boom of the apparatus-21 e., the hoom which carries conduit L, and Y is the construction-boomi. 6., the boom having to do with the placing of forms, reinforcing-metal work, etc. on the building that is being constructed; the boom X being connected with the eye m of carriage W in the track P, and the boom Y being connected with the eye at of the car; riage W in the track R. The boom X is referably shaped in cross-section as shown 1n Fig. 14 and is designed to extend downwardly from the tower at about the angle shown in Fig. 1.- Fixed to the inner end of 105 the boom X, referably in the manner shown in Fig. 2, and extending at an acute angleto said boom X, is an arm Z to which are connected cables A A through which the boom is maintained in position and moved as occasion demands; the cable A being carried over a sheave A, and thence down to any suitable power or manual means A for taking up or paying out the cable A As will be readily appreciated, the de- 115 scribed arrangement of the .arm Z, relative to the boom X, is materially advantageous inasmuch as it affords considerable leverage in the maintainence of the boom X in the position shown and in the raising and lower- 120 mg of said boom.

The conduit L which extends through the boom X, Fig. 14, may be and preferably is formed in sections detachably connected by wires in the manner shown at the top of 125 Fig. 9 or in any other approved manner, and obviously said conduit may be of any desired length to extendto any oint in the length of the boom or beyond t to outer end of the boom. The outermost section 1 of 130 pipe section B of Figs. 9 and 10 may be used in lieu of the pipe sections L and B the said section B bemg connected in a swiveled manner to the outermost sectlon Z of'conduit L, and being of a greater size in cross-section for a portion of its length than the same, this latter in order to lessen theliability of the conduit L becoming choked.

The before described pan K is arranged on and connected by wires 6 or other suitable means to the boomL in position to receive from the pipe G, and the reduced end of said pan K is suitably connected with and arranged to discharge into the conduit L Fig. 7.

The construction boom Y is maintained in the position shown by a guy cable C extending between its outer end and the tower A, and is toothed at its underside, as indicated by 0 On saidboom Y is arranged a traveler D which carries a pulleyvblock E and a dog lever F, the latter having a comparatively heavy arm f adapted to engage the teeth 0 and also having its other arm connected to a cable Gr which ext-ends to the ground. going that an attendant standing on the ground is enabled through the cable G3 to move'the traveler D outwardly on the boom Y; also, that when the cable G is relieved of pull the arm f of lever F will fall away from the teeth of the boom, this latter in order to permit of the traveler being drawn inwardlyon the boom after a load has been raised throu h the medium of a cable H which extentis through the pulley blockE and another pulley block I and is designed to be taken up and paid out by suitable power or hand means. J

It will be gathered from the foregoing that when the carriages of the booms X and Y are held at one corner of the tower the booms can be oscillated to encircle threefourths of a building, and then by shifting the boom carriages to the other corner of thertower and there fastening the same, the booms may be moved to reach to the other one-fourth of the building. Itwill also be It will be manifest from the fore-- the boom, a conduit carried b ,means for raising plastic material to a suit- D, one man to manipulate the lines of the booms, and thrce men to supply and set materials and tamp walls, etc.

As before stated, the construction herein shown and described constitutes the best practical embodiment of my invention of which I am aware, but it is obvious that in the future practice of my invention various changes in the form, construction and relative arrangement of parts may be made within the scope of my invention as defined in the claims appended.
